I blanked egr myself so I know egr is blanked off.
Might need fap off thou. I have changed every ecu etc. vin is 9hx. Ecu's are 9hx. 9hx had no dpf. So it's just cat but can bypass that later. The 9hy had dpf. Get anti-pollution message sometimes before startup for some reason!. I also know there is slight passing of oil from turbo and there is play.
Possible injector nozzles or turbo!
Car is more than likely over 100k (No speedo for years) lol.
Hope this sheds more light to try fix.
Maybe just adjust smoke limit on map!
Cheers
